The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As Figure 1-Figure 8, a kind of LED filament support, two pins 1,5 that comprise substrate 3 and be connected to substrate two ends.Described substrate is the waveform (thin slice of substrate undulate) with a plurality of lateral openings, the opening direction of part lateral openings is arranged (being the left side of Fig. 1) towards the left side of substrate, the opening direction of another part lateral openings is arranged (being the right side of Fig. 1) towards the right side of substrate, above-mentioned two parts lateral openings space arrange (according to one towards left opening, one towards right opening, one towards left opening, one towards right opening ... mode arrange, by that analogy).In each lateral openings, be all fixed with one for the pallet 7 (size is determined as required) of LED chip is installed, pallet and substrate adopt same metal to make, for example copper, aluminium, stainless steel, pallet and substrate can adopt the sheet metal of vertical bar shaped one-body molded by Sheet Metal Forming Technology.
As shown in Fig. 3, Fig. 6, described pallet is towards the back side depression of substrate, depression position is in the form of slot, the front (being the front of bottom land) at depression position is the stationary plane 7-1 of described LED chip (stationary plane is plane), this stationary plane is positioned at the rear side of substrate, between stationary plane and the back side of substrate, keeps certain distance, and the light that LED chip sends is except penetrating towards front, can also, from the back side of the space directive substrate between stationary plane and substrate, increase the brightness of substrate back.
The two ends of described pallet are separately fixed at the both sides of the openend of lateral openings, and between pallet and the bottom of lateral openings, keep certain distance to form a loophole 8 (size is determined as required).Described loophole is projected as any (in Fig. 1, the Fig. 4 for C shape) in circle, rectangle, rhombus, triangle, polygon, C shape in the plane parallel with substrate, or offers into as required other shape.This loophole can reduce substrate to the stopping of the light of LED chip, the light that LED chip sends can be penetrated to substrate back more, and the brightness that further improves substrate back makes circumferential 360 degree of LED filament luminous equably.Still it should be noted that, above-mentioned openend be lateral openings for example, near the one end at substrate edge: opening direction is towards left lateral openings, and its openend is left end, and bottom is right-hand member; And opening direction is towards right lateral openings, its openend is right-hand member, and bottom is left end.
In described two pins, have at least the end of a pin to be connected with the end of substrate by plastic connector 4; As shown in Figure 1, one of them pin 5 is connected with an end of substrate by plastic connector, and another pin 1 is one-body molded with another end of substrate.
As shown in figure 12, described substrate and pin are shaped with respectively at least one flexure plane 11-2,11-1 in plastic connector, the position of flexure plane and shape are determined as required, in Figure 12, the flexure plane 11-1 of pin is the cylinder shape of protruding to the back side, and the flexure plane 11-2 of substrate is the arc surface of tiltedly stretching to substrate back.
The end 3-2 of described substrate and the end 5-1 of pin are shaped with respectively at least one external part 9, and the interlock (interlock but do not contact) of mutually staggering of the external part of substrate and the external part of pin; Stagger mutually at fore-and-aft direction in the end of described substrate and the end of pin.The quantity of the external part of aforesaid substrate and the external part of pin is definite as required, and because plastic connector size is less, so the quantity of the external part of substrate and the external part of pin is recommended as 1 (as shown in figure 11).The external part of aforesaid substrate and the external part of pin are in the interlock of mutually staggering of the left and right directions shown in Figure 11.The external part of substrate stretches out upward towards pin, the upper end of the external part of substrate is through the cross section F-F of the external part lower end of pin, simultaneously, the cross section G-G of the external part upper end of substrate has also been passed in the lower end of the external part of pin, thereby makes arbitrary cross section of plastic connector all have metal reinforced.
Between the external part of the external part of aforesaid substrate and the end of pin and pin, all keep a determining deviation, between the external part of the external part of pin and the end of substrate and substrate, also keep a determining deviation to realize insulation, above-mentioned spacing is 0.1-0.2mm, recommend 0.15mm, within this segment distance, filling the plastic cement of plastic connector with isolated substrate and pin.
Figure 15 shows that the flitch of LED filament support described in the utility model, on this flitch, be arranged side by side with a plurality of LED filament supports 6, the connecting portion 2 of the pin of all supports upper end and support flitch upside is connected as a single entity, the connecting portion of the pin of all supports lower end and support flitch downside is connected as a single entity, and can obtain the LED filament support of varying number by different cutting methods.The structure of above-mentioned connecting portion and the cutting method of connecting portion and existing LED filament support flitch are similar, at this, do not describe in detail.
